| 中文摘要: |
| 为了解决模态测试设备面向模态参数的校准问题，研究了模态分析与模态叠加理论，根据该理论得到一个闭环模态信号控制算法，由该闭环控制算法构建一个由5台激振器构成的闭环系统，该组激振器模拟模态测试过程中的一组信号，此组信号包含了标准模态参数的信号，最后用该组信号来校准模态测试设备。根据该方法进行了数值模拟和试验测试，结果显示该校准方法是可行的，并且可以脱离具体的模态结构，不同模态信号的模拟也可灵活实现。 |

| In order to solve the problem of modal parameter calibration of modal test system, the modal analysis and modal superposition theory are studied. According to this theory, a closed-loop mode signal control algorithm is proposed. The closed-loop system is composed of 5 exciters. According to this method, the numerical simulation and experiment test are carried out. The results show that the calibration method is feasible and can be separated from the concrete modal structure, and the simulation of different modes can be realized. |
